Automating Immersive Reading

smoores•about 3 hours ago

I took a week of from work recently to reimplement Storyteller's forced alignment algorithm. Storyteller[1] is an open source, self hosted platform for creating, managing, and reading/listening to "readaloud" books — books that have audiobook narration built in and can highlight each sentence (and/or word, with this new algorithm!) as it's read aloud. Forced alignment is the process of determining where each piece of text starts and ends in the audiobook.

Anyway, I am really pleased with how the new algorithm turned out! Hopefully someone else finds it interesting as well.

This is excellent! I wanted this. I had noticed that Kindle had limited feature like this for certain books that support audiobooks. I had tried this style of reading with audiobook and ebook without a any automated sync, but hadn't pursued it. This looks cool. :)

Thanks! We're improving it all the time — we're working on big new releases ("v3") for the web app and mobile apps. There's a Discord server linked in the docs if you ever need any help out want to chat!

This is really impressive! One thing I’ve often wanted is a way to listen to an ebook (say, while cooking), and then later be able to sit down and read from where I left off. This essentially requires the same functionality that Storyteller offers (syncing progress through an ebook and audiobook), though arguably overkill for this use case (since I could handle a more coarse alignment). In any case, is this something Storyteller would be good for? Or are there other tools for the job?

Storyteller works great for this. It even syncs your position across devices. So when I really want to settle in to read, I go ahead and switch from my iPhone where I was listening to my Boox e-ink reader which syncs right to where I left off.

That is actually the exact use case that I originally built Storyteller for! I wanted to listen to my books on long runs, and then switch to reading when I got back.

The Storyteller mobile apps have great support for this, I think. They have fully fledged audiobook players and ebook readers, and you can switch between the two with one tap. And then of course you can also double tap on a sentence and start playing from there, with the app highlighting the currently read sentence.

What about reading on a koreader? Is bookbridge still the best bet?

i think smoores response got flagged for some reason, but there’s a StorytellerSync plugin https://github.com/Sirozha1337/storytellersync.koplugin

I generated an immersive reading for Athenaze in a few afternoons with Claude
